SIGNALING SYSTEM.

Specification of Letters Patent.

Application filed December 24:, 1913. Serial No. 805,522.

To all whom i1, may concern Be it known that l, Cwnnxoe E. BEACH, s citizen of the lliiitecl States, residing at llinghanlton, in the county of Broome and finite of New York, have inrentecl certain new and useful Improvements in Signaling .ll i'stems, of which the following is a speciiicetion.

My invention relates to signaling systems and particularly to alarm systems for protecting localized territory and for protecting buildings, such, for example, as footory buildings end factory premises. Systerns of this l'incl are designed to provide means for sending an alarm, such es an alarm of fire; from any of a number of stations and to give Warning signals at various points in a ouilcling or premises to warn the occupants to escape therefrom.-

Une object of my invention is to so connect the clifiercnt signal stations that if two or more are operated at the same time, such operated stations will take control of the system through their non-interference magnets in a predetermined order, usior example, the lower of the operated stations first. and then, itmorc than two were operated, the others in corresponding order, thus Warning those above the fire that their escape is likely to he cut off end haste is therefore necessary, While re: 1ss.uring those below the lire that they may safely give the right of Way to persons from-the upper floors.

:rnother object of my invention is to so connect the different signal stations that if a signal is already being transmitted "from a station 021331 upper floor and a station on a li'uver floor-is operated, the upper stetion will, for like reason, stop at the end tion transmit its signal Without clciey.

iinother ob ect of my invention 1s torrevizle such mechanism in thesignsl time that if two or more are operated at or count the some time, the signals from all of then 1' will be transmitted in :1 predetermined'orcler, without interference one with another.

Another object of myinvention is to make possible the use or" a series of electromagneticelly ofiere'ted signal devices require" electric current, such as mg apowerful I single stroke direct acting bells, shunting hells, motoror magnet-driven horns, etc,"

controlled from a plurality of signaling smdevice 6 with its battery 7.

In United States Patent No. 1,662,38 issued to me under date of May 20, 1913 is shown a method of si sling from 2. si a'igle station, by reversing t -e current-in the signal i'es'ponsii'e part of the circuit While sllowing the current in the rest of the circult to flow in the normal direction. The present invention is an improrcmerit c or that described in the above patent in its adaptation to the use of e' plurality of soninterfering successive signaling stations. v

My present invention is particularly rlesigned for utilizing inexpensive signeliug boxesat the verious stations, es, .5502 e ainple, those known in the as sector boxes, which may be Wound during the operation of pulling and which are cepsble of running for a limited number of rounds arrongetl in a vertical series. .At each, of

these stations, a signal receiving clevicemoy be installed, this device being shown single stroke hell 1 at station C and represented at the other stations lgy suit-dole devices At one end of the series cistetions I provide the current source 3 and utthe opposite end. electrically, -l pro iitle two suitable resistances 4 and 5. resistances are shown es magnets 'edeptecl to control the connection of asuitableelerm The signaling mechanism in'stolledet each of the stations isshown diagrammatically in Fig. 2.

Asshoii n in Fl .2, the sector o ierated driving train for the signal Wheel is adopted,

The pull leverlfiis connected with the 'ouiicl eech .time the box is pulled, ,enti when released rotates the, signs wheel a. ipredeterminedtnumber of times.

ing its left hand end sector gear 9 and the spring 10 is provided to be wound when the sector is swung downwardl and to restore the sector when released. he details of the driving train are not shown,-,as any well known mechanism may be used having interposed ratchet connecting the sector gear and the signal wheel 11 to transmit motion to the signal wheel only during the movement of the sector in'one direction. Associated with the signal wheel is the signaling lever 12 having a projection cooperating with the teeth of the signal wheel 11. This lever has the insulating stud 13 for actuating the contact springs 14 and 16 which are connected toether by bar of insulating material. dhese springs co'dperate respectively with contact springs 15 and 17. Secured to gear on the signal wheel shaft is a pin 18; The prop lever 19 has an insulating stud 21 adapted to move and hold the contact spring 22 a suitable distance away from contact spring 23 while said prop lever is in a certain position. a

A curved projection from prop lever 19 extends into the path of the pin 18 and said projection is so located that at a suitable time after the last tooth of the wheel 11 has disengaged the lever 12, the pin 18 will engage said projection and quickly operate the lever 19 to move spring 22 out of contact with spring 23. Said projection from lever 19 is of such form that it will thereafter hold said spring 22 out of contact with spring 23 until just prior to the engagement of the first of the teeth of the wheel 11 with the projection on the signaling lever 12, and so that when said pin 18 disengages said projection from the lever 19 it will permit said lever 19 to instantaneously move to the position in which it permits spring 22 to make contact with spring 23. The non-interference elcctromagnet 24 has an armature structure 25 pivoted at 26 and havcxtending into the path of arm 20 of the prop lever 19. When the prop lever 19 moves in the direction where by it will permit spring 22 to move toward sprin 23, the lower end of said arm 20 is brought into cngagen'icnt with the armature (i0 spring 22 said springs.

tact spring structure 25 to hold said armature structure in attracted pos1t1on.

An arm 27 extends from the armature structure so that when the armature struc-' ture is in retracted position, this arm engages pallet lever 28 and thereby stops the train, and the relation of said arm 27 to the pallet lever 28 must be such that when the lever 19 is moved by pin 18 to separate from spring 23, arm 27 will not engage lever 28 until after the separation of T be free end of contact spring 30 has in the path of insulating pin 29 carried by the sector gear 9. The con- 31 is so mounted that its free end is normally not in contact with the spring 30, but when the sector 9 is started downwardly upon winding of the spring, the pin 29 allows spring 30 to make contact with spring 31.

Referring again to Fig. 1, current normally flows from the source 3 through wire 32 to contact 15 at station A and serially upward through similar contact 15 at all the other stations, thence through resistance 'magnet l to wire 33 and serially downward through contact 23 at each station, to and through wire 34 and serially upward through contact 22, non-interference magnet 2 1 and contact 30 at each station, to and through wire 35 and serially downward through contacts 31 and 17 at-each station,

thencenpwam through wire-36 to and -thro'u'gh the '37" andserially downward throughthe signal receiving devices 1 and 2 at each station, to and through wire 38 and serially upward through contact 14 at each station, to andthrou h resistance magnet 5, to and through wire 39 and serially downward throu h contact 16 at each station. to the other si e of source 3. The

, winding of the non-interference magnets 24;

and the resistance ma ets 4-. and 5, is such that they will be su ciently energized to draw their armatures'into attracted position when energized by a current which is insul'ficicnt to cause magnet l and the mag nets provided in the devices 2 to actuate their armatures,.'the resistance of said magconstant test and securing non-interference between the various signaling stations. As

the armature of both magnets 4 and 5 are' normally attracted, the ircuit'of alarm 6 is open and the alarm does not sound. If the main circuit should be interrupted or they main source 3 should-fail, the armatures 'ot;

magnets 4 and 5 will {be retracted to close the circuit of alarm 6. 'It ujill thnsye seen that whenever the current flow iitis ulj liindin circuit is insufiici'ent, the nounced by alarm 6. a;

It will be noticed that each contact spring is provided with two terminals and the wires to these "contact springs are separatelytached, one to each terminal. By thus making the material ofthe contact spring itself an essential part of the normal closed circuit, it is impossible to have a loose contact at any terminal without indicating the same through failure of magnets 4 and 5. Itwill be seen that such crosses in my systerm as might be most likely to occur will be indicated through the short circuiting of the fact lie I ris at- I d the consequent opera,

nci iiie pulled at or about the same time, is'as follows :';In the event that the box located at station A was pulled and subsequent to the pulling of said box and before said box came to rest, the boxes at stations B and C were pulled, the first movement bf the pin 29 of the box at station A would permit its asso-'' ciated spring to move into contact with its spring 31 and thereb shunt the noninterference magnets 24: 0 the boxes at stationsB and C through the following path: from the spring 30 in box A to wire 34 and therein through spring 22, magnet 24, and spying 30 of boxes B and C, to wire and therein through springs 31 and 17 of boxes C and B to spring 31 in box A, which is in contact with spring '30 therein. The result of thus short-circuiting the non-interference magnets of the boxes at stations B and C will be to permit their armature structures 2527 to move into retracted position and thereby prevent the running of these boxes. After the conclusion of the intended number of rotations of the signal wheel 11 of the box at station A, the pin'fll) associated therewith will move the contact spring-3'0 away from the associated contact spr ng 31, thereby opening the short circuit hereinbefoi e described. between the springs 30 and 31 of the box at station A will not cause the energization'oi' the magnet 24 of the box at station C owing to the shunting of said magnet by the similar action of springs 30 and 31 in the box at station B when that box was pulled. However, the opening of this short circuit at station A would result in the energization of the magnet 24 in the box at station B and thereupon said box would proceed to run until its signal wheel had been rotated the intended number of times, when the pin 29 associated with the box at station-B would move its contact spring 30 away from the associated contact spring 31, thereby opening .the short circuit of magnet 24 of the box at station G. From the foregoing it will be seen that if two or niore boxes are simultaneously pulled, the box at-the lowest location will immediately shunt the magnets 24 of the higher boxes which will. thereby be prevented from running untilthe lowest box has completed its intended' rru'n. It will further be seen that whenfthe magnets 24 of two or more boxes have beemshunted by the pulling. of a lower box, and the boxes having such shuntedmagnets have been pulled,

after the conclusion of the intended run of the lower box, the shunt will be removed from the magnet 24 of the lowest waiting box, allowing this box to run, but the other box or boxes will be prevented from running until this second box has completed its intended run, when the remaining boxes will be successively released in like ord r.

The reeu lt{if magnets of the boxes at 'stationsB. andIA will be to permit theirarmature structures 2527 to move'into retracted position and thereby prevent the running of these boxes.

Inasmuch as me e jet 24 of the box at'sta-tion C was shujited w "en the boxes at stations A and B were pulled,

- through the action of their spring'30 and 31',-

the armature structure 25 at said station Gis permitted to retract upon the lift ng of the lever 19 just described and in soj'retracting will move its arm 27 in the path bf its lever 28 and thereby stop the runnin of the box I at station C. The opening'of t e short cirj cuit' between the springs 22 and23 at station C will not cause the energization of the agnet 24 at station B, owin to the shunting of said magnet by the 'sprmgs30'and 31'dn the box at station A when that box" was pulled. However, the opening of this short circuit at tation C would result in the en-' ergization' of the .magnet' 24 in the box at station A and thereupon said box would proceed to' run until its signal wheelliad been rotated the intended number of times;

when the'box at station B would be per; mitted to run. through the operation already described. When the wheel 11 at station B has been rotated its intended number of. times, the shunt around the magnet, 24; at

station C would be likewisef'renioved, where borhss enga' arness:

upon drumming of saidibon would he resumedl, From-thefotegoing'it will be seen that ifJt-hefirst tooth of the-Wheel 11 of any 'thesignaling lever 12 essocietcdtlierewith, the pulling of any box or boxes located-below such running box will not'ceuse therrunning of'ssid upper box to be interrupted'until after the lost of the teeth of its-wheel'll has disengaged its signaling lever" 12. It will further be seen that under-these circumstances the runnning of such lower boxes will be restrained until afterthe'lest of the teeth of the wheel 1] of the'uyper box' has disengaged the associatcdsi mlin lever @12 Whereu on said re- 5 g p strained hoses will follow in succession, the host at lowest location always talrin pre ccdence as'alresdy described. Thus, tie 0peration-ofthe portion of my invention prorideu for the purpose of securing non-interference and succession is such that the sign from the lowest point of fire danger is gi. e right of Way, with a minimum delay, nals. example, a fire might start on a lower floor of a building, the smoke going through: some vertical opening to an upper floor sndthere meking'itself known. If a ho on theupper floor was first operated, the hon on the lower floor, when operated, would detain the upper box at the end of the current round, and immediately transmit its mvn signal,

The operation ofthe portion of my invention provided for the purpose of causing the actuation oi the signal receiving devices inclnc ed in the Wire 37 is as follows: During the rotation or signal Wheel 11, the teeth thereof are successively broughtinto engagement with signaling lever 42 The operation of this lever causes the closing and opening of contact springs 14, 15 and l6, 17. When these cont-acts are closed current may llo'w from source 3 through wire 32 to spring 15 in the operating box, Where it divides into three branches, as follows 1) from spring 15 through spring 14, downward in viire 38, upward in Wire 37 through signal receiving devices 2 and 1, downward in wire upward in wire 35 to springl? in the V operating box to spring 1-6 therein (2) from spring 15 in the operating box, upward through Wire 32, through magnet l, downward in Wire 33 to spring in the operating box, spring magnet spring 30, spsing 31, and spring 1? to spring 1 3 therein; s d {3) from spring 15 in the operating hos through spring 14:, upward in W1re 38, through magnet 5, downward in wire 39 to spring 16 in the operating boxhere the three branches join and the current returns to source-3 downward through Wire 39. On

account of the great diminution of the resistance oi? the path including the signal re ceiving devices 1 and 2, the current passing 1 there can be no confusion of sig;-,

,be dispensed Wl' through said devices will he nth creased and will constitute the Inner por tion of the total flowfrom source 3, the restraining eilect of resistance magnets-'4: and

5 being. suiircientto reduce the leakage is around said signaling devices 1 and 2 to an insignificant amount.-

It will be noted thet'the test current normally flows through the Wire 3? in the o posite direction to the signaling current which flows through said Wire While the springs ll, l5 and 16, 17 are in contest, which has a very beneficial efi'ect in that it tends to overcome and neutralize any. residualmagnetism in the'magnet l and in the devices 2. In practice, this results in much more accurate operation of all signaling devices used in this circuit. An important i-dvuntage obtained through arrangement that an accidental interruption of the circuit will not cause the signsl receiving devices 1 and 2 to not, thus avoiding unnecessary confusion and disturbance, while at the some time, such breaking of the circuit will afiect magnets 4 and 5, thus indicating at the alarm 6 a disturbance to the circuit.

the use of this 'lhe action of the contact springs la 15 v and 16, 17 will only vary the current in the magnets l and 5, but not at any time interrupt or reverse the direction of said current through these magnets, and signals can, therefore, be transmitted by means of these contact springs without affecting the alarm 6.

While I have chosen "to refer to the various sign-sling; stations as being located atvarying altitudes, l have only done so with the idea of securing clearness of description,

but it will be obvious to those skilled in the art that the physical location of the various signaling stations is of no consequence out that the desired sequence of operation is obteined by the order in which the mechanisms of the various stations are electrically con-' nected. F or like purposes of cleurncss l have shown and described the magnets l and as having sufficient resistance to produce the required resiilts, but these nmgncts may be of much lower resistance and a suitable separate resistance seriull; connected therewith, and many other similar changes may be made in the construction and arrangement of my invention Without departing from the spirit thereof.

While I consider it desirable to provide releiys for controlling the alarm '6, if it is deemed unnecessary to provide two relays. a suitable resistance nfay be substituted for either the re istunce magnet l or the resistance magnet 5 and the remaining relay will give an effective test of the continuity of the entire circuit, and if desired both relays may and suitable resistances substituted for the magnets thereof and under these circumstances the condition of the circuit may, if desired,'be determined or indicated by a suitable measuring or current detecting instrument included at any convennnt point in said circuit, or by using thearmature of the non-interference magnet as an indicator or to operate any well known indicating mechanism suit-able therefor.

The signal station mechanism shown in Fig. 2 is provided for'the purpose ofmore clearly disclosing the operative relations of the various in'strumentalities shown diagramaticaily in Fig. l, but any signaling mechanism arranged to .suitably operate similar instrumentalities may be used in place thereof, and such mechanism does not form part of my present invention.
